Data (paired comparisons with undecided and forced NAs): Negative Attitudes towards Immigrants

Description

A survey of 98 students was carried out to examine student's (negative) attitudes towards immigrants. Four statements had to be compared with regard to higher acceptance. The four statements were

• Foreigners increase crime rates (crimRate)

• Foreigners take apprenticeship training position away (position)

• Foreigners are a strain for the social welfare system (socBurd)

• Foreigners threaten our culture (culture)

The first 6 variables in the dataset indicate the preferences of the students. For a given comparison the responses are coded by 1 if the first item was preferred, -1 if the second university was preferred and 0 if no decision was made. The variable ENG characterises the knowledge of English and the variable SEX characterises the gender.
